Description

[Detailed description of the invention]

0001

FIELD OF THE INVENTION The present invention relates to a holder for stabilizing ampoules for injection.

0002

BACKGROUND OF THE INVENTION Medications for injection are usually supplied in glass ampoules having a body, a stem, and a constriction or neck in between. This glass ampoule can be easily broken by grasping the ampoule separately and applying force to the neck and snapping it to separate the stem and body. I can do it. One problem in this case is that when the ampoule is broken, the user risks cutting his or her hand due to the jagged edges of the glass in the process of breaking the ampoule or after breaking the ampoule. Furthermore, while operating the syringe with one hand, it is necessary to hold the opened ampoule with the other hand, but depending on the situation, it is desirable to be able to stand the ampoule in a stable state and to have both hands free.

0003

SUMMARY OF THE INVENTION Accordingly, the present invention eliminates the risk of the user cutting his/her hand due to the ampoule, and also solves the problem of the user having to operate the ampoule with one hand.

0004

[Means for Solving the Problems] Accordingly, the present invention provides a body,
Provided is an ampoule holder for glass ampoules having a stem and an intermediate waist or neck for folding, the holder having a body portion configured to receive the ampoule body and a head portion configured to receive the stem of the ampoule. The main body and head are connected by a hinge, and each can be separated from the other by snapping the stem and body of the ampoule apart. It is designed to protect each part of the ampoule when cleaning.

Ideally, the hinge is located diametrically opposite the break link. This break-away link can be formed as a narrow, thin section connecting the body of the holder to the head. This link breaks when enough force is applied to split the ampoule stem from its body.

Preferably, the hinge is formed from at least one piece of flexible material connecting the head of the holder to the body. In a preferred embodiment, there are two spaced apart hinge pieces, with a portion of the material extending from the head or body to an intermediate area between the two hinge pieces. Such a material attachment serves to further increase safety in reducing the possibility of the user's fingers coming into contact with the glass ampoule. Whether there is one or two hinge pieces, it is desirable that they extend into the cut portion of the head and/or the end of the body. This extension of the hinge piece moves the head further away from the body, making it easier to access the contents of the ampoule through the broken neck.

In one variation, the hinge can be formed as a pair of flexible arms located generally diametrically opposite each other. Ideally, the flexible arms are interconnected between the respective upper ends of the body and the head, thereby allowing the head to be moved completely away from the body. Preferably, the flexible arm is in the form of a bellows.

[0008] At least the hinge of the holder has good static memory (such as a styrene blend) so that the hinge piece remains in its new position when the head is folded to expose the opened ampoule. It is desirable to do so.

In a preferred embodiment, the body is formed with an open bottom for insertion of an ampoule. Preferably, the opening at the bottom thereof is provided with an inwardly directed bulge or projection, over which the lower part of the ampoule is pushed, and which bulge or projection is formed to hold the ampoule. . In addition, the head is provided with an inner rib for gripping the stem of the ampoule, so that the ampoule is positioned correctly within the width of the holder, so that the neck of the ampoule is attached to the hinge of the holder (and the broken link if there is one).
It is desirable that the ampoule stem be located on the same line as or above the ampoule so that the stem of the ampoule will not fall when the ampoule is split open. The rib preferably extends in the longitudinal direction of the head, and the inner surface of the rib extends along its length.
It is desirable to form them so that they are substantially parallel to each other. This prevents the stem of the ampoule from being ejected outside the head of the holder.

[0010] A finger grip surface can be provided on the outer surface of the head and/or body. The bottom of the holder is preferably provided with a removable bottom plate to increase the stability of the holder when the holder is erected on its bottom.

[0011]

[Example] Although the present invention can be implemented in various forms,
A preferred embodiment thereof will be described with reference to the accompanying drawings. In that drawing, the ampoule holder shown in FIGS. 1 to 3 consists of a body part 1 and a head part 2 interconnected by a pair of hinge pieces 3 and a breakable link 4. The broken link 4 is made of a thinner portion of the material constituting the holder, and has a shape as shown in FIG. The hinge piece 3 extends into the cutout 5 of the body part 1 . In use, the glass ampoule 7 is inserted, stem first, through the opening 6 in the bottom of the main body 1, and the protrusion 8 (projecting inwardly) extends through the body of the ampoule.
(see also FIG. 6) until the lower end of the ampoule snaps over this protrusion, the stem 10 of the ampoule being gripped into the head 2 of the holder by an internal rib or striation 11. As a result, the ampoule is held across the width of the holder and the neck 9 of the ampoule is located on the same line as the breakage link 4 or slightly above it. The head 2 of the holder is inclined inwardly towards its closed end, while the inner surfaces of the ribs 11 are formed parallel to each other over their entire length. There is no action to force the ampoule stem 10 out of the head 2 of the holder.

The ampoule is pushed up until the shoulder at the upper end of the body of the ampoule 7 abuts against the curved hinge 3. The bottom of the ampoule is thereby lifted onto the top of the projection 8.

In order to gain access to the contents of the ampoule, the holder is grasped with two hands and force is applied to the finger grip surface 13 on the head of the holder, thereby breaking the breakage link 4 and breaking the ampoule. The stem 10 is cut off at the neck 9, while the head 2 is bent over by the hinge piece 3. This hinge piece (and the rest of the ampoule holder as well) is constructed from a styrene blend material that has excellent static memory, thereby allowing the head 2 to hold the ampoule when the hinge is bent to a new position. 7, allowing unobstructed access to the contents of the ampoule. After being broken, the body of the ampoule 7 falls onto the protrusion 8, whereby the sharp end of the broken glass falls below the upper end of the main body 1, further ensuring the protection of the user. Become. Due to its flat bottom 14, the ampoule holder can stand on a flat surface. Separable bottom plate 15 (Figure 7) to further ensure stability
and install the bottom part of the ampoule holder therein.

The hinge part of the ampoule holder can also be modified to include "webs" 16 between the hinge pieces 3, as shown in FIG. This allows the hinge pieces to be spaced far enough apart to further protect the user from the broken glass portion of the ampoule 7. Ampoule shown in Figure 8
A variant of the holder has a head 2 connected to the body 1 by a pair of flexible bellows-shaped arms 17. This arm 17 is connected to the upper end portions of the main body portion 1 and the head portion 2, respectively. The arm 17 normally holds the head and body approximately on the same line, but can apply force between the head and the body to break the head of the ampoule in the holder. The head surrounding the ampoule stem is pushed to one side by a flexible arm 17, allowing access to the interior of the ampoule body.

[0015]

[Effects of the Invention] If the ampoule is inserted into such a holder, the user will be better protected since the glass itself will not be grabbed when the stem of the ampoule is broken. If the head of the holder is shaped specifically to hold the stem, the head and body of the holder may be interconnected by a hinge so that the two parts of the ampoule can be separated after the ampoule has been broken. It is possible to keep parts together. However, as a variant, the hinge can be easily broken in subsequent processing, so that the head containing the stem can be completely separated from the body of the ampoule. The holder is designed to have a relatively stable bottom, allowing the ampule in the holder to stand on a flat surface, leaving the user's hands free to manipulate the syringe. Become. The stability of the holder can also be increased by attaching a removable bottom plate that fits the bottom of the main body.
